To allwhom itmag concern: I .1 I I Be it known that I, ENR UEVILLARREAL, a citizen of Mexico, residing at New York,

in the county of New York and State of New York, have invented new and useful Improvements in Knife-lViping Attachmentsfor Type-CastingMachines, of which the following is a specification.

The invention relates to wiper attachments. I I

More particularly to attachments especially designed for use on a linotype machine for wiping the slug trimming knife 'of'the machine.

Some of the'objects of the present'inven .tion are: tosimplify' -devices of the char-i acter mentioned, by reducing the number of parts; to produce a more thoroughly efficient device; to inake the operationfof a linotype machinesafe for the operator by arranging the device between the vise and the mold 'disk ofIt-he casting mechanism of the machine .to make provision for increase ing "the wiping operations of the device duringone complete .cycle ofthe operations of theema'ohine to which. it is attached.

lVith these andj o'ther' objects in view theinvention resides in the particular provision, relative dispositionand operation of the parts hereinafter more fully described" and illustrated in the accompanying drawis supported for operation on the vise forming a part of the casting mechanism, and is 7 arranged between the said vise and the mold disk. The knife 10 for trimming the slugs after they are ejected from the mold boxes of the disk 11-, forms a part of the'said vise.

The device comprises a bar 12 which is arranged for movement with respect to the knife 10; The bar 12 is supported for movement by the mold banking block 13 and the lower end thereof is confined in a guide opening in a part of the vise bracket Specification of Letters Patent." -Application filed Apri1 9,-1921. serial No. 453,912; A

orframel The upper end o'f the-b ar' f l2 has attached thereto the wiper 14. Marthe] upperend of the bar the same is provided witlr an elongated slot 1 5 r A pin 16 "extends transversely through 'the slot ligand the ends of the pin 16 are supported by parts ofthe'block 13: The? pin 16 permits the up and down movement of the bar 12" V and prevents the displacement of the-"same..

Some distance" above-the lower" extremity of the 'bar 12 .theretis arranged a s'top block' 17 which limits the *ClOWnWail movement of the bar 12; The W per'l i p I contact and traverse'the trimming-edges or the knife 10; in the reciprocation offthe' bar" 12 to we n is attached The bar 12 is movecl-upwardlypositively it moves gravity.

, The" upward 1 movement of? th'ejbar. 121s effectedby the employ'inentiof a lever:l18fl f which is pivoted as at -19-toa1part of thej" vise frame. One end of-the lever 18 has;v

connection with the bar 1 2 -the::,lever"{ is slotted as at 20 and} 2t pin 21*carried the f bar12 extends in the said slot; fTheoppo site 'end of the lever "18 carries a pin:22

which is 'under'the influence -off ajspring 23. Infthe normal position of thelever 1'8, the pin 22 lies in the path ofmovement of the element 24' secured to the face of the mold disk 11. The molddisk. has an I T intermittent"v movement. The disk rotates and'm'oves toward and from the vise frame.,-

The disk. 11. moves" away from [the vice moves toward the viseframe -'f0r"the slug casmg and e ectingoperation. Because of the necessity that the diskll move toward and from the vise frame, the pin22 is arranged ment, When the disk 11 moves toward'the action of its relatedspring 23, and when on the lever 18 to have reciprocatory move-a 'vise framie the pin 22fmoves againstlthe I 1 frame forth'e rotationoperation,and'tlre disk 7 the disk 11 moves awayf'rom the vise frame, f: thespring'23 moves the pin 22 back to its' normal position in which it is disposed to J be engaged by the element 24 on the mold disk- 11 In the rotation of the disk'11,-alt

a predetermined time, the element 24: en--' gages the pin 22 and moves the end. of they lever 18 carrying the pin 22, downwardly, Y and the opposite end of the lever upwardly,-

causing the bar 12 and its wiper 14 to move upwardly. At the end ofthe upward movement of loar 12,pin22 movesou tof contact 1 with element 24. In the upward movement of the wiper 14, the same, in contact with the trimming edges of the knife 10, wipes thesame clean of all adhering particles or trimmings. It should at once be obvious that by embodying more than one element 24 the wiper let may be caused to wipe'the trimming edges of the knife 10 more frequently. It is within the present invention to" employ any number of elements 24. V J n e i I v From the foregoing it should be manifest that, a simple and more efliciently serviceable device has been disclosed; that under its relative arrangement, the element of danger to the operator is. entirely elimi-,

nated.

What is claimed is:

1. A device as characterized including a movable bar, a wiper carried by the bar, means for moving the bar upwardly, guiding means for causing the rectilinear movement of said bar, the said bar being free to gravitate downwardly to a normal position.

'2. A device as characterized including a movable bar, a wiper carried by the bar,

means for moving the bar upwardly, guid- I ing means for causing the rectilinear movement of sald bar,v the said bar being free to gravitate downwardlyto a normal. position,

and means for limiting the downward movement of the bar.

'8. A device as'characterized including a mo'vablebar, a wiper carried by the bar, and means for moving the bar upwardly, the said bar being free to gravitate downwardly to a normal position, said means including a pivoted. lever, a pin carried by the lever, and a movable element which travels in a path in which the said pin lies normally.

4. A device as characterized including a movable bar, a wiper at the upper end of the bar, and 'means for moving the bar upwardly, the said bar being free to gravitate downwardly to a normal position, said means including a pivoted lever loosely connected to said bar, a pin carried by the lever, and a movable element whichtravels in a path in which the said pin lies normally.

' 5. In a type casting machine including a vise frame and a mold disk having com poundmovement, a slug trimming knife on said frame, a movable bar, a wiper carried by the bar and disposed to traverse the tr1m.-.

ming edges of the saidknife in contacting relation therewitl1,'means for moving the bar upwardly, the said vbar being free to gravitate downwardly, said means includ ing a pivoted lever loosely connected to the bar, a spring pressed pin carried by said lever, and an element carried by said disk which travels in a path in which the said pin lies normally in the rotation of said disk and means for limiting the downward movement of said bar.

6. In a type casting'machine. including a vise frame and a mold disk having compound movement, a slug trimming knife on said frame, a movable bar between the said frame and the said disk, a wiper carried by the bar and disposed to traverse the trimming edges of the said knife in contacting relation therewith, .means for moving the bar upwardly, the said bar being free to gravitate downwardly, said means including a pivoted lever loosely connected to the bar and arranged between the frame and mold disk and supported by the frame, a spring 7 pressed pin carried by said lever, and an element carried by said disk which travels,

in a path in which the said pin lies when the lever is in a normal position, the said element engaging said pin 1n the rotation of said disk to actuate said lever; and means for limiting the downward movement of said bar.

In testimony whereof I hereby aflix my signature.
